A window is being replaced with tinted glass. The plan below shows the design of the window. Each unit length represents 1 foot. The glass costs $12 per square foot. How much will it cost to replace the glass? Use 3.14 for π.
Answers
Answer:
The image of the window can be seen below:
In the image we can see that the window can be separated in:
One rectangle of 4ft by 5 ft
Two half-circles (that if we add we get a complete circle) of diameter D = 4in.
First, we know that for a rectangle of length L and width W, the area is:
A = L*W
Then the area of our rectangle is:
A = 4ft*5ft = 20ft^2
And for a circle of diameter D, the area is:
A' = 3.14*(D/2)^2
In this case we have D = 4in, then the area of the circle (that we get when we add the areas of the two half-circles) is:
A' = 3.14*(4ft/2)^2 = 3.14*4 ft^2 = 12.56 ft^2
Then the total area of the window is:
Area = A + A' = 20 ft^2 + 12.56 ft^2 = 32.56 ft^2
And we know that each square foot of glass costs $12, then 32.56 square foots of glass will cost 32.56 times $12
Then the total cost is:
C = 32.56*$12 = $390.72

Answers
Answer:
7+√5/4
Step-by-step explanation:
if that is = a, find the value of a + 1 over a
Given that a = 3 - √5
a+1/1 = (3-√5)+1/3 - √5
4-√5/3 - √5
Rationalize
4-√5/3 - √5 * 3+√5/3 + √5
= 12 +4√5-3√5-√25/9-5
= 12+√5-5/4
= 7+√5/4
Hence the requred answer is 7+√5/4

An article costing GH 2000.00 is sold at a
profit of 60%. Calculate the selling price
of the article.
Answers
Answer:
GH 5000
Step-by-step explanation:
Given data
Cost price= GH 2000.00
Percent profit= 60%
Sales price =???
The sale price can be found as
% profit= sale-cost/sale*100
60= sale-2000/sale*100
60= 100*sale-200000//sale
60*sale= 100sale-200000
1000sale-60sale= 200000
40sale= 200000
sale= 200000/40
sale= 5000
Hence the sales price = GH 5000
Cindy's square-shaped garden has side lengths of x ft. She will plant 5 tulip bulbs per square foot. Write a function g to model the number of bulbs she should plant. How many bulbs will she plant if the garden has a side length of 8 feet? for this problem what is the function we need to write g(x)=?
Answers
Answer:
The total number of bulbs are "320 bulbs".
Step-by-step explanation:
According to the question,
The square garden's side length,
x = 8 feet
Number of tulip bulbs she plant,
= 5
Now,
As per the question, the area of square will be:
⇒ [tex]A=x^2[/tex]
[tex]=(8)^2[/tex]
[tex]=64[/tex]
hence,
The total number of bulbs will be:
⇒ [tex]n=A\times 5[/tex]
[tex]=64\times 5[/tex]
[tex]=320 \ bulbs[/tex]
Thus the above is the correct solution.
